Constructor Details

Variation

public Variation(MemorySegment address)

Create a Variation proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Variation

public Variation(Arena arena)

Allocate a new Variation.

Parameters:

arena - to control the memory allocation scope

Variation

public Variation()

Allocate a new Variation. The memory is allocated with Arena.ofAuto().

Variation

public Variation(Tag tag,
 float value,
 Arena arena)

Allocate a new Variation with the fields set to the provided values.

Parameters:

tag - value for the field tag

value - value for the field value

arena - to control the memory allocation scope

Variation

public Variation(Tag tag,
 float value)

Allocate a new Variation with the fields set to the provided values. The memory is allocated with Arena.ofAuto().

Parameters:

tag - value for the field tag

value - value for the field value

Method Details

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

readTag

public Tag readTag()

Read the value of the field tag.

Returns:

The value of the field tag

writeTag

public void writeTag(Tag tag)

Write a value in the field tag.

Parameters:

tag - The new value for the field tag

readValue

public float readValue()

Read the value of the field value.

Returns:

The value of the field value

writeValue

public void writeValue(float value)

Write a value in the field value.

Parameters:

value - The new value for the field value

variationToString

public void variationToString(@Nullable Out<String[]> buf)

Converts an hb_variation_t into a NULL-terminated string in the format understood by hb_variation_from_string(). The client in responsible for allocating big enough size for buf, 128 bytes is more than enough.

Note that the string won't include any whitespace.

Parameters:

buf - output string
